shyouhei b515528271 re-introduce __builtin_add_overflow ... r57789 (74cdd89) was gradually "improve"d by naruse through r57793 to r57806, resulted in reverting the efect of r57789 while retaining its complexity. I think the current situation is slightly worse than before (same output complicated source code). Here I introduce __builtin_add_overflow again, which (I think) is what naruse wanted to do in r57793. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57807 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2017-03-08 04:50:22 +00:00
